PhysTechSoft continued development on their own and released PTS-DOS v6.6 somewhere between and presented PTS-DOS v6.65 at the CeBIT
exhibition in 1997. The next version from PhysTechSoft, formally PTS/DOS Extended Version 6.70 was labeled PTS-DOS 2000 and is still being distributed as a last 16-bit PTS-DOS system, .
Paragon continued their PTS-DOS line and released Paragon DOS Pro 2000 (also known and labeled in some places as PTS/DOS Pro 2000). According to Paragon, this was the last version and all development since then ceased. Moreover, this release contained bundled source code of older PTS-DOS v6.51.
Later, PhysTechSoft continued developing PTS-DOS and finally released PTS-DOS 32, formally known as PTS-DOS v7.0,) which added support for the FAT-32 file system
